The jet grout columns extend from the founding elevation
to approximately one metre above the existing water
table. Above this, timber lagging is installed from existing
grade during excavation.
To provide structural support for underpinning the
existing subway station, six 1,500-mm-diameter structural
caissons will be installed 40 metres deep. A welded wide
flange beam and rebar cage will be installed to reinforce the
caisson, allowing connection of the underpinning beams to
the caisson foundations. CTS will self-perform the entire
underpinning operation.
Once all of the vertical drilling scope on the south side
is complete, the team will install a traffic deck consisting
of steel deck beams welded to the piles within the south
side secant wall and founding on a temporary strip footing
installed on the north side.
Lateral bracing welded to each adjacent deck beam will
facilitate load transfer while in operation. An engineered
timber mat will be secured on top of the deck beams to
complete the deck. Traffic will then be diverted to the south
side while the surface work begins on the north side.
Finally, when the north side is complete, the north deck
beam will be bolted to the south deck beam installed earlier,
allowing four lanes of traffic to open back up to the public
while excavation advances below. With excavation performed
by CTS, Keller will install soil anchors, walers and
struts to provide lateral support of the excavation.
After reaching the underside of the TTC subway tunnel,
the team will continue excavation and lateral support work
towards the west and east ends of the station while CTS
